Abstract

For the past 50 yr, practices for ex situ preservation of endangered breeds have been extended. Semen and primordial germ cells, gonadic tissues have been frozen to create genetic stocks of chicken genetic diversity in cryobanks. Semen cryopreservation stays the preferred method since it is not...

Abstract

The study aimed to evaluate the reproductive traits in poultry breeder with different weight ranges of two semi-heavy lineages. The experimental method was completely randomized design in factorial arrangement (3×2) with two factors: reproductive methods (artificial insemination and natural mating) ...

Abstract

The ability to produce viable progeny is a complex trait, involving both male and female components. In poultry, mating ratios are usually 1 male to 6 to 12 females. Consequently, the impact of male reproductive failure is much greater than that for a female. In this study, the genetic...

Abstract

The aim of this study was to determine the role of fatty acids for sperm survival in the sperm storage tubules (SSTs) of the hen oviduct. The mucosa tissues of uterovaginal junction (UVJ) of White Leghorn laying hens with or without artificial insemination using semen from Barred Plymouth Rock...

Abstract

Objective: This study was conducted to compare morphological defects, viability, motility (MOT), fertility (F), and hatchability (H) in four Korean native chicken breeds (KNCBs), and to evaluate whether defective segments of spermatozoa are associated with MOT, F, and H. Methods: Four KNCBs,...

Abstract

Avian sperm are stored in the sperm storage tubules (SSTs) of the hen oviduct for a prolonged period. However, the precise mechanisms by which sperm are kept alive in the SSTs are still not fully understood. The aim of this study was to determine whether exosomes are secreted by SST cells and play...

Abstract

The turkey industry relies totally on artificial insemination to continue and improve production. If something compromises the insemination process, such as contaminated semen, it becomes a detrimental loss to the industry. Bacteria have been found in broiler breeder males to reduce sperm motility. ...

Abstract

A series of experiments was designed to evaluate the quality of cryopreserved rooster sperm and its fertility so that programs needing to bank germplasm and recreate animals can do so utilizing a minimal amount of cryopreserved semen. In experiment 1, rooster semen from the National Animal...

Abstract

90 White Leghorn (W.L.) ♀♀ were inseminated with semen from 2 W.L. and 2 Red White-tailed ♂♂ Egg fertility in the periods 2-6 and 2-11 days after insemination was 86.8 and 64.0% resp. from vaginal inseminations, and 68.4 and 52.9% from intra-peritoneal inseminations; corresponding figures for...

Abstract

350 White Leghorn pullets were inseminated with semen from 10 White Leghorn ♂♂. Ejaculate volume averaged 0.209 ml., and sperm number per ejaculate was 30 x 106 to 60 x 106. Of 24, 883 eggs set, 89.31% were fertile and 81.42% hatched.
